RO®-X Tactical Radio

Uninterrupted communications for crucial situational awareness

Global Handheld SATCOM Connectivity

The RO-X tactical radio, based on L3Harris AssuredReach™ technology, is a ruggedized handheld device that provides on-the-move (OTM), over-the-horizon (OTH) secure voice, data and position location information (PLI) to disadvantaged users.

The RO-X tactical radio uses the Distributed Tactical Communications System (DTCS) provided by USSF’s Enhanced Mobile Satellite Services (EMSS) office to instantly communicate with other DTCS users anywhere in the world. 

Similar to a secure “walkie-talkie” the RO-X radio does not require ground infrastructure. The talker can reach thousands  of other authorized users anywhere in the  world with line of sight to the sky. 

Communication occurs over a distribution of secure nets. An individual RO-X radio may be a registered member of up to fifteen nets. Secure voice communication is available to any registered DTCS radio, including other RO-X tactical radios, radios equipped with the DTCS Mission Module, as well as the more than 15,000 currently fielded RO tactical radios.

Equipped with an embedded GPS receiver, each RO-X tactical radio transmits and receives voice, data and GPS over a single antenna. Encrypted PLI is transmitted with flexible configurable options to meet operational requirements. 

The RO-X provides integrated USB, Wi-Fi and Bluetooth capability that gives users the flexibility to easily interface with a variety of standard accessories. This flexibility also provides the user the ability to use an Android device as a wireless speaker mic when line of sight to the sky is not available to the RO-X. This is achieved through the use of a simple Android app.
